全释硬科技丨地球会失重7秒？科学家：这是谣言！

Core Viewpoint - The warning about a global disaster caused by gravitational waves during the solar eclipse on August 12, 2026, is a complete fabrication and has been debunked by scientists [1]. Group 1: Misconceptions about the Solar Eclipse - The rumor claims that a black hole merger will generate gravitational waves leading to a global gravity anomaly lasting 7.3 seconds, potentially resulting in 40 million casualties [1]. - The solar eclipse itself is a natural phenomenon where the moon temporarily blocks sunlight, having no impact on Earth's gravitational field or orbital mechanics [1]. Group 2: Clarification on Gravity and Gravitational Waves - The term "gravity anomaly" is misused; astronauts in the Chinese space station experience weightlessness not due to a lack of gravity but because they are in free fall, maintaining a speed of approximately 8 kilometers per second in orbit [2]. - Gravitational waves are extremely weak signals that require highly sensitive instruments for detection, and the idea that they could cause global disasters is a gross exaggeration [2].
